Shares of Lockheed Martin (NYSE: LMT) traded up more than 5% on Wednesday after the defense titan's CEO expressed confidence that pandemic-related disruptions to production lines would be short-lived, and that the Pentagon budget will remain robust for years to come. Lockheed Martin and other defense contractors have been relative safe havens during the COVID-19 pandemic, but the company has seen some supply chain and manufacturing disruptions on key products, including its F-35 Joint Strike Fighter. CEO Marillyn Hewson, speaking Thursday at a Bernstein conference, said that Lockheed Martin will deliver 18 to 24 fewer F-35s than planned this year due to the pandemic.

Shares of Lockheed Martin (NYSE: LMT) rose 4.76% on Monday, as the F-35 manufacturer gained altitude along with the broader market. Investors are feeling optimistic thanks to some promising early results on a potential coronavirus vaccine, lifting hopes that the worst of the COVID-19 pandemic will soon be behind us. As industrial stocks go, Lockheed Martin has weathered the pandemic pretty well.

Lockheed's advances comes as the Pentagon has increased the amount of interim payments it makes to defense contractors in an effort to give them a financial boost amid the pandemic. The company has hired over 3,400 new employees in the United States since the pandemic began, and said it remains on track with its plans to hire 12,000 new employees by the end of the year.
